  1. Gloves and Hand Protection for Welding

    In the world of welding, besides our eyes our hands are the most important tools we have in our personal tool bag. Taking care of our hands is just as important as taking care of her eyes so, just like we need to have the proper safety glasses on our face, we need to have the proper gloves on our hands as well. Before we pick out the proper gloves, we need to make sure we understand the potential hazards that there could be, so we understand what they should protect us from. ANSI Z49.1 contains information about personal protective equipment and other safety gear in and around the welding and cutting industry. 

    The hazards to our hands in the welding world are numerous. We can have our hand smashed or crushed if they get caught or pinched between two objects. We can cut our hands from exposure to sharp edges and other jagged surfaces. We can burn our hands from red hot metal, sparks and other hot flying metal. Gloves also protect our hands from th

  3. 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.

  4. 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.

  6. 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

  7. 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

  8. 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

  9. 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

  10. 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.
