#BLUE COLLAR BRILLIANCE HOW TO#

Filler metal or weld metal selection is key. The most important thing, to me, that a welder knows is when something can't be done safely or completely.

#BLUE COLLAR BRILLIANCE HOW TO#

You have to see it to know how to react or adapt. You know that a gray or purple color means the weld pass exceeded the satisfactory temperature, and could cause problems like carbide precipitation.Įverything welds. the color of the weld will tell them if they were too hot or too cold. There are things welders know, like when welding stainless. It all depends on the positioning of the weld.

This technique repeats itself until you are finished.ĭepending on where the weld is located, the welder may hold the filler wire around the backside of the pipe and feed it through the gap, called 'backfeeding' or he could aim the filler wire into the back side of the bevel edges while holding it in front as well to produce a similar effect. so you start to break down the edge of the bevel wall, add it to your weld pool, and then you add your filler metal one side of the joint, pivot to the opposite side, keeping the weld pool fluid, and add filler metal there after breaking down that edge of the bevel. Any welder worth his balls knows this moment and changes techniques.

There comes a point where you can't just push the wire into the puddle anymore. As the gap widens, I start to push/feed more filler wire into the weld pool. I would start by laying the wire in the gap and welding over top of it. but they all know the end result needs to be a root face at least flush or up to 1/8' of reinforcement. Let's say it starts with a 1/8' gap on bottom, and ends up 3/8' on the top side. the fit up is square but the gap is jacked to shit. An easy example would be: putting in a root pass on a 4' pipe. They usually end up in a change of technique, mid weld. Any experienced welder will handle it satisfactorily, but someone fresh out of school may not have that knowledge. Many things done 'on the fly' are corrections of something fucking up.
