Splatter problem
 

Finally..... finished my manifold today. Had to make the wastegate runners, etc :wallbash:


What's the cause of splatter? I hate it, I got my mig welds sizzlin like bacon yet I have splatter everywhere :wallbash: Yes, I'm using gas.

Is there a way to fix or help this problem? :wallbash:

Im not seeing any pics

no pics

slow down the wire feed, or dirty metal would be the first things that come to mind

like crackhead said above slow down the wire feed and i am assuming your welding ss using ss wire, Stainless steel always splatters, even more if it is cast like sch 40, but you can go to a local welding supply store and the have a product i cant recall the name off the top of my head but its in a tub and its green that when the tip of your gun is hot you dip it into the stuff and it will dramatically reduce the amount of splatter you get

just my 2 cents.

Thanks, yeah it's ss tubing with ss wire. Thanks for the input guys :)

You can't completely get around spatter when MIG welding. If you use a product called "anti-spatter," similar to what was mentioned above, it will not allow the spatter to actually stick to the parent metal.

How far away are you holding the tip from the weld? The closer the nozzle, the less spatter you will have. Also, hold the gun "pulling" at about 20-30 degree angle. Too much angle also induces splatter. I second the wire speed too. It's very easy to MIG, but very difficult to do it correctly. Also, stay on the leading edge of your puddle without stepping out of it too far. It will actually give you better penetration than stepping outside of the puddle. Trust me, I used to be the king of "cold lap." Keep a tight pattern and work the puddle. This will allow you to turn down the voltage and speed while keeping penetration, which will help with the splatter.

i weld pulling also, and backstep every 1/4 inch or so and 'aftercool' the weld,


IE i let up enough on the trigger to stop the feed but still keeps the gas on, keeps hot spots from bubbling up if you do it right

i had to modify my walmart lincon welder to let me do this, basicly just notched the trigger where the momentary swtich hits so the gas comes on first
