MIG Welding: The Basics for Mild Steel
2010/6/1· When MIG welding mild steel, you can use either the push or pull technique, but note that pushing usually offers a better view and enables you to better direct wire into the joint. Travel angle Normal welding conditions in all positions call for a travel angle of 5 to 15 degrees.
AFT carries a range of screw clamps, also known as worm drive hose clamps, which are commonly used in a variety of appliions in addition to the pneumatic uses it was designed for. Our 1/2" wide stainless steel clamps meet all ANSI/SAE J1670 specifiions.
Core (manufacturing) - Wikipedia
If Fub≤0, no chaplet is used. If Fub>0, chaplets is used. As mentioned earlier, cores are usually supported by two core prints in the mold. However, there are situations where a core only uses one core print so other means are required to support the cantilevered end.

Welding - Wikipedia
This cored wire is more expensive than the standard solid wire and can generate fumes and/or slag, but it permits even higher welding speed and greater metal penetration.  Gas tungsten arc welding (GTAW), or tungsten inert gas (TIG) welding, is a manual welding process that uses a non-consumable tungsten electrode, an inert or semi-inert gas mixture, and a separate filler material.
