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 !!!!

The Anatomy Of A Fillet Weld For Short Circuit (Solid Wire) MIG.

Short Circut Transfer MIG is a great tool for the home hobby welder. The Fillet Weld is very important to learn.


CLAMS is also a handy tool for the hobby welder to learn along with some other basic terminology.

GMAW is where this post originates from, the video linked is a common instructional tool in some welding schools.

WIKI link to a Fillet Weld.

A few links to DIY weld testing.

"The macro etch test can provide some excellent feedback especially when it is done immediately after welding, while the image of the puddle is still in the welders head."

Welding Tips and Tricks, a great resource !

Macro Etch.


With any type of welding the most important part is practice.

HAPPY WELDING !!!

Boilermakers Local 102, I finally got in at Vigor Fab.

After nearly 2 years I finally got the dream job, I am a welder for Vigor Fab in Seattle WA.

This ship yard does a lot of work and I am excited to be doing something new !
I will try to post photos of some stuff as I find time .

HAPPY WELDING !!!!
