Welding Cost Reduction Revisited
Control flow shielding gas flow rates – For processes that require shielding gas make sure no more flow than necessary is used. Too much flow will waste gas and can even create weld defects. For GMAW typical flow rates will range from 25 – 50 cubic feet per hour; however, we constantly see flowmeters that are pegged, running 100CFH+.

T oday we received two different requests for help pertaining to shielding gas selection. The first caller requested a chart that tells them what materials can be welded with the different shielding gases that they had. They wanted a chart that can be provided to the welders to make sure they used the right gas on […]

What Changes To A WPS Require Requalification - WELDING …
Switch from 75/25 to 90/10 argon/CO2 shielding gas – Table 4.5 (19) requires a change when the gas composition is changed exceeding code limits. In this case a change of more than 10% of the minor component requires requalification. Also, this change allows ABC to go from globular transfer into spray transfer.

I n our previous article we mentioned that a customer was inquiring about running their 98% argon / 2% carbon dioxide (98/2) shielding gas on mild steel. This gas is used on stainless as it maintains the amount of reactive gas (in this case CO2) under 3%. Our quick answer was “yes, you can weld carbon […]
WELDING ANSWERSShould You Consider a Different Shielding …
GMAW (mig welding) uses shielding gas to protect the weld puddle from the atmosphere while in a molten state. This is general knowledge, but many in our industry believe this is the only function of the shielding gas. Shielding gases can affect welding in many different ways and an evaluation of your current choice of […]

2024年10月8日 · They are typically considered “hard to weld” because they are crack sensitive and are susceptible to undergoing significant changes in their physical and mechanical properties after welding. However, high carbon steels can be welded successfully and without problems by having a sound understanding of the […]

T ig welding can produce beautiful looking welds, and more importantly, x-ray quality deposits on some of the most critical welding applications. For the beginner it may be a very intimidating process. Selecting the right tungsten (type and size), cup size, and shielding gas and gas flow can be a daunting task. Below is a quick […]
