Hitsausvirran

Hitsausvirran refers to the welding current, a crucial parameter in electric arc welding processes. It is the flow of electrical energy through the welding circuit, which melts the filler metal and the base material, creating a weld joint. The magnitude of the welding current directly influences the heat input into the workpiece and the consumable electrode.

The appropriate welding current depends on several factors, including the type of welding process being used (e.g., Stick welding, MIG welding, TIG welding), the type and diameter of the electrode or filler wire, the thickness of the material being joined, and the desired weld penetration. Too low a current will result in insufficient heat, leading to poor fusion, weak welds, and potential porosity. Conversely, too high a current can cause excessive melting, burn-through of thin materials, distortion, and increased spatter.

Welders often adjust the welding current using controls on the welding machine. Some machines have simple amperage settings, while others offer more advanced control over voltage and wire feed speed, which are indirectly related to the current. Understanding and correctly setting the welding current is fundamental to achieving strong, sound, and aesthetically pleasing welds. It is a key variable that operators must master for successful welding.
