starting with the welding process itself, ultraviolet and infrared rays are emitted not just from the welding arc but also from the molten metal. and, both uv and ir are extremely hazardous to your eyes. however, what is more likely to be more dangerous for a welder’s eyes is debris from the grinding, brushing or chipping process before or,cleaning stainless after weld,the trick is to brush the weld while it's still hot- discolouration comes right off as the parts you're working with are small another method would be to avoid any weld colour. argon is heavier than air- fab up a shallow tray out of stainless, fill with argon (add a fitting at the base to pipe in argon) and weld the parts in it.
many welders get flu-like symptoms after welding. the effects are often worse at the start of the working week. metal fume fever is usually linked to welding or hot work on galvanised metals. high exposures to mild steel weld fume can also cause this illness. metal fume fever does not usually have any lasting ill,grinding or sanding aluminum,grinding or sanding aluminum. by lawrence date 05-18-2007 09:20. right on tommy. a chunk of parafin (about $1 per pound in the canning section of your local grocery) will save thousands of dollars in ball burrs. just hit the parafin with the burr and grind, rehit the parafin every few moments and the thing will last 50 times longer than without
using an angle grinder with a flap disc works great to prep steel for mig or tig welding. mild steel does not require the surface to be super clean to get a good weld. in the picture above you can see the left side is brand new untouched steel, it may look clean but it,shielded metal arc welding machine parts and process,smaw (shielded metal arc welding) is a welding process in which the source of heat coming from the electrical current. this heat is the result of the conversion of electric power that is converted into heat when the electrode is attached to the base metal. the meeting between the electrode and the base metal will cause ion exchange.
