Heat Affected Zone. (Another Short Circuit GMAW post)

I believe I have mentioned this before, but it seems like a topic that needs too be re-visited.

What is the HAZ or "Heat Affected Zone?" The HAZ is the area surrounding the weld. This will effect the temper of the base metal, usually weakening it in the area surrounding the weld.

This is due to a metallurgical change in the base metal surrounding the welded area.

When we weld we use heat to do so, to much you blow through, to little and no fusion, just right better know a little about how a weld will distort you'r base metal before you start a big project that needs to be structural.  CLAMS is all I have to say.

What type of wire are you using and do you know what all that ER70S-6 stuff means? Selecting the correct consumable for the job is the most commonly overlooked factor in producing a quality weld that I have seen on the many repair jobs I have done.

I need more coffee,
                                                                 HAPPY WELDING !!!!
