The devil is in the details, especially when it comes to welding processes. This technology area has information on consumables, including cutting tips, electrodes and wire, spatter prevention compounds, temporary purge dams, and welding torch components.
Q: We're a small shop that builds and welds a lot of custom metal products. In many instances, the products are made from two or three different material combinations, including stainless steel at times. Is there a good rule of thumb for deciding the correct filler metal to use? A: That is a...

Being as comfortable as possible on the job is important for mind, body, and productivity. Customizing your GMAW gun for the application can improve your personal comfort and weld quality.
Q: We're a job shop and much of our work is customized or unique. Because of this, we have to work with multiple welding codes and sometimes we have to verify welding procedures. We have been bidding on some new projects that have welding crack tip opening displacement (CTOD) requirements. How is...

Overheating is a symptom of what could turn into catastrophic gun failure. Striking the right balance between gun size and capacity can increase the efficiency of a welding operation and decrease problems, like overheating, that could damage the equipment.
What guidelines should a job shop follow in regards to heat input if there is no welding procedure to fall back on? The Consumables Corner team has the answer.

Welders are judged by the appearance of their beads, the strength of their welds, and their ability to pass visual and technical inspection. So why shouldn’t you scrutinize your GTAW torch components in the same way that you or someone else would scrutinize your welds? If your GTAW torch doesn’t pass inspection, there’s a good chance that your welds won’t either.

Q: We manufacture various products for the agriculture and transportation industries. A majority of our products are made from 6061 and 5652 aluminum and are joined with gas metal arc welding (GMAW-S) using a 5356 filler metal and 100 percent argon shielding gas. Most of the joints are partial...
Q: We need to weld a 1-in.-thick AISI 1050 carbon steel plate to a 2-in.-dia. A514 steel shaft. The AISI 1050 has a yield and tensile strength of 95 KSI and 115 KSI, respectively. We know we should preheat, but we're unsure of what temperatures to use or what filler metal to select. Could you...

Argon and CO2 are the most commonly used gases in gas metal arc welding (GMAW). Alone, each has pronounced advantages. Together they combine to neutralize each other’s weaknesses and capitalize on each other’s strengths, all while providing you with your desired weld requirements.
Using the right-sized contact tip is critical to achieving optimal results in robotic and semiautomatic GMAW operations. Among the factors that determine the right tip size are the process and wire.

Like all arc welding processes, submerged arc welding (SAW) requires the right consumables for the specific application to achieve optimal results. Are cored wires right for yours?
Q: We're a construction equipment manufacturer that is finding that our customers increasingly require more components designed and manufactured from high-strength steels such as A514 or 4130. This means we have to preheat and follow slow cooling conditions, but even then certain joints or...
