  1. A welding task: some tips you should read about

    Welding is not an easy job and every commercial welder will confirm you that. The welding tasks, no matter if they require usage of filler rods, tig welders or plasma cutters, stick welder or plasma welder they all require full commitment of the energy, attention and focus.

    This means that the welder should be 100 % concentrated in the task one performs and to make his or hers hand and wrist totally relaxed. Of course everything comes with practice and that is why the new people in the welding profession require not only a welding certificate taken after two years of study, but also a lot of hours actually welding different things and practicing.

    The good commercial welders know that in order to become true professionals they need to make their hand relaxed and to watch the weld pool. This is especially important when performing mig welding but is also valid when practicing aluminum welding, cutting torch, metal cutting and metal welding, steel welding, etc.

  2. Certifications for Commercial Welders and Industrial Welders

    Both commercial welders and industrial welders are entitled to get the so called welder certification or welder qualification. When the commercial welder has such a document, this means that this welder is capable of creating welds under specific welding procedure that are of excellent quality.

    The certification of the commercial welder is based on certain special tests that determine one’s skill and ability to provide a sound weld metal. The welder tests can be different and can be quite specific depending on the type of the metal, type of the material (if not metal), joint design, thickness, as well as welding process including arc welding, mig welding, tig welding, etc.

    In general, the test is done in accordance to the particular code and are usually administrated by the American Welding Society and the American Society of Mechanical Engineers. The commercial welding equipment of some manufacturers also can come with its own standards.

  4. The positive aspects of the commercial welding job

    Becoming a commercial welder is what many people want, however there are yet much more people that would be good at that profession and yet they do not know it yet. Welding is being taught at schools and special courses and those young men that want to make a career in commercial welding or industrial welding first have to earn a structural welding certificate and be taken on the construction site or in the field.

    Welding is a profession that is paid well, gives the workers a lot of freedom and has many advantages which appeal to those people who do not see themselves working from nine until five for five days in the week. At the same time learning how to weld and be good at that is not easy and the job is associated with a lot of risk and dangers.

    The welders can work on many sites including repair shops, black iron plants, fields, etc. They will be better off in case they have joined the International Association of Bridge Structural, Ornamental and Re-Enforcing Ir

  5. The basic terms used in welding

    Welding industry has its specific welding terms that each commercial welder has to be aware of. Of course, there is no need learning the entire welding vocabulary, yet one should get acquainted with some of the major terms, such as:

    Arc Cutting – process that can be done with a 6010 or 6011 rod with a very hot machine. It is where you cut through the steel using the force of the arc.

    Automatic Welding - a weld made by special equipment.

    Flash Burn - This is a radiation burn from the ultra violet rays from the welding arc. The flash burn is similar to sunburn and it starts hurting hours later, being very painful to the eyes.

    Machine Welding – the weld is done by machine and is inspected by a person.

    Manual Welding – welding by an actual person. In stick welding, the welder holds the stinger, processing the welding electrode and controlling the we

  6. Storage of electrodes

    Every commercial welder knows that the storage of electrodes is very important when working with welding materials and performing a certain welding process. In the stick welding the commercial welders and the industrial welders are using rods.

    These are welding electrode rods which are covered with flux. During the Second World War it was discovered that the coatings on the filler rod make the weld better and stronger. It is a fact that in the past on the production sites and on the ships, the bare metal rods were used in flat position.

    The rods were stored outside and were not taken care of that much. As they were stored in the open air, the rods were often covered with rust and a welding made with this rod turned out to be stronger and better. The people who were learning how to weld and experimenting with new methods made a discovery.

    The commercial welders made experiments with

  7. Bonded Fluxes and Fused Fluxes

    There are many types of flux core items that are used in the different welding processes and activities. Among all the different types of fluxes that are used in the Sumberged Arc Welding, two types are most widely spread – the fused flux and the bonded flux, each of them having its advantages and disadvantages. Each commercial welder has its preferences based on one’s experience and practice. However, down the page we will explain the characteristics and the advantages of the two types of flux core.

    The fused fluxes

    When the commercial welders and the industrial welders are making fused fluxes, the raw materials that they are using are dry mixed together, after which they are fused and melted into a liquid state by a very high temperature furnace. When the fusion is complete, the fluxes are then cooled. This can happen by using big chill blocks or by using a stream o

  8. The process of Submerged Arc Welding

    Originally developed by the Linde – Union Carbide Company, the submerged arc welding process is widely used in the rigs of beams, booms, etc. Deferent by the open arc welding process, the submerged one is performed under a protective flux blanket.

    What does this means? It means that the arc is being constantly covered, which eliminates exposure towards arc radiation and usage of welding screens. So, how is actually the process of submerged arc welding done?

    The submerged arc welding is done in a fully automatic or semi-automatic manner. The arc is flat and is maintained between the weld and the bare wire electrode. The electrode is fed into the arc when it is melted.

    The commercial welder will tell you that at the automatic process of submerged arc welding, the set of rollers is driven by a controlled motor so that the wire is fed into the arc at a speed rate that is absolutely equivalent to the rate at which the electrode is melting.

  9. The MIG welder 115 volt field test

    Every commercial welder and each industrial welder is tested for MIG welding.  The test is known as the 115 volt field test. There is a special 115 MIG welding machine, which is a good option for the welder who wants to weld with shielding gas. This machine is welding with a 3/16"" thick tee joint with multiple passes, where the machine is plugged into a 10 amp 30 foot reel extension cord. This is not a very good practice as the commercial welder should not use a light duty extension cord with a MIG welder, but it can happen in reality.

    So, what happened? The result was a small 20 inches straight sputter after welding. The welding could be fine when it is used a self-shielded flux core Lincoln nr211. In other words, the tests proved that the commercial welder cannot predict how a MIG welding machine will behave and weld just by looking at it, without trying. The MIG AHp welder that has been used

  10. TIG Welding of stainless steel

    In case a commercial welder decides to perform a TIG welding task with stainless steel on a stainless plate, there is a few things to consider. In case the welder tries to weld the two parts in a free state with no restraint, then at the end the plates will not be flat. Actually, the stainless steel will always warp when it is being welded. The role of the commercial welder here is to make everything possible for the distortion to be just to an acceptable level. In general, there are a few things that the TIG welder can do in order to minimize distortion when TIG welding stainless. The main thing is to make the puddle established as quickly as possible and get moving. The amperage should not be tapered any slower than needed.

    It is a fact that the stainless steel has a low thermal conductivity, and the heat builds up quickly, so the TIG welding stainless quickly make
