i am open to constructive critisism as it is a key tool for improvement.,

Looks good, What are you doing to clean the metal before welding?

 

wire wheel. any suggestions on how to properly prep the metal??

ive noticeed some of my welds are a bit contaminated sometimes.

fishing for a few tips here

 

I use acetone to prep the metal,it doesn't leave any residue.

 

nice, good looking

 

What is your gas set at also ? are you using a stainless steel wire brush?

 

15 lbs

 

yep, acetone works, dupont makes a product called Pre-Sol, like acetone but a little less toxic.

looks good

 

How many passes did you make?

 

thats one pass.

 

The weld is VERY porous. Increase your gas flow, use a bigger cup, and lower the heat. Schedule 10/40 should require 2 passes to get decent penetration. One pass will cause either severe undercutting or poor penetration and both will more than likely result in having to blast the material with heat resulting in poor weld quality.

 

thanks. im using a number 6 cup right now. think 20 lbs is better gas flow wise??

i appreciate the comments, keep em coming

 

approx amp suggestion for sched 10?

 

I use 18# and a gas lens.

 

You can put it to 25-30lbs.

 

kick *** man

 

Pretty Good............. Pretty... Pretty... Good!!!

 

ill giev you 1 tip. clean the metal. jeezuz thats dirty. also a bit hot there buddy. wheres the color ? color is your key to knowing wahts giong on with the metal properties. if its gry you burned off all properties of the metal and thus .. have weakened it

 

You need to prep the basemetal better and do it in two passes with a lot less heat. If you search enough in this forum you will find a thread by engloid that shows how it's done.

 

after 2 pages, all the trwads are tossed,

i didnt see it.


thanks for the tips
