Welding Rod What Is. It is designed to be used with DC power at a normal polarity. The areas of its application include farming sea activities such as ship repair and construction mining and construction.
A welding rod is a stick of filler metal used to join materials together during the welding process. During welding a welding machine creates an electric arc that travels out through this rod and on to the material being welded. The areas of its application include farming sea activities such as ship repair and construction mining and construction.
It can get very confusing especially for someone who is new and just started learning about the basics of welding.
The electrode is made up of materials which are similar to that of the metals chosen to be welded. By looking at the classification we already know that the 7018 welding rod is an all-position rod which produces weld beads which can withstand 70000 pounds of stress per square inch. Also known as welding electrodes these are the metallic rods that melt to create a bond between two or more pieces. Welding is a fabrication process whereby two or more parts are fused together by means of heat pressure or both forming a join as the parts cool.
