Default Re: Welcome To The Welding & Metalworking Forum

The weld puddle always moves in front of the tungsten (TIG) or nozzle (MIG) regardless of the thickness of the is never "pulled"...the penetration of the weld is controlled by the angle and speed of the tig torch/mig gun , the heat setting and the amount of filler material (wire) added to the puddle..when welding Aluminum , the mixing of the shielded gases , Argon and Heliumn in the right proportions also affect the penetration of the weld...when looking for the best quality of steel welds it would be an Argon and Co2 mix..
