The actual trick to welding thin metal would be to use a cable feed. Just kidding, this suggestion is to describe how to perform it using a stick welder. A cable feed or tig welder is excellent for sheet metal, however, we'll assume you don't need one. We will need to establish what's deemed thin metal.
The very first thing to work out is what type of welding rods and what dimensions of welding sticks to utilizing. In case you've got fine new 1/8" substance, you would go with 3/32" 7018 sticks. In case you've got old rusty painted 14 judges, you would tend to utilize 1/8" or 3/32" 6011 sticks. If you want to know more about welding then visit this website.

You may inquire; why not simply grind off the rust? Well if it's only surface rust proceed, but when it is pitted out you'll grind all of the stuff away until you get it blank. Also, but if you're simply doing a fast repair job on something, only weld it. Odds are if the substance is that poor the weld will outlast the remainder of the material anyhow.
If you should drag the pole slowly, you'll have a fairly good prospect of burning. If you're welding vertically, do not be reluctant to conduct the 6011's downhill. In the event the material is thin, utilize the whipping motion downhill too. It goes against some fundamentals of burying slag however, once the substance is thin it does not matter just as much.
Say for example you're minding an air compressor tank which has a hole rusted inside. You may weld the patch 100 percent since it has to be airtight, but not for power. If you're earning a part of an air duct, then you'll weld it strong for air rather than for power, you have the point.
