laskohitsaus

Laskohitsaus, also known as lap welding or overlap welding, is a joining process where two or more overlapping metal sheets are welded together. The edges of the overlapping pieces are fused to create a strong seam. This method is distinct from butt welding, where the edges are placed end-to-end.

The primary advantage of laskohitsaus is its ability to create a sealed joint, which can be beneficial in preventing leaks of fluids or gases. It also provides good structural integrity, as the overlapping material distributes stress across a larger area. The process can be performed using various welding techniques, including arc welding processes like shielded metal arc welding (SMAW), gas metal arc welding (GMAW), and gas tungsten arc welding (GTAW), as well as resistance welding methods.

Laskohitsaus is commonly used in applications where watertight or airtight seals are required, such as in shipbuilding, automotive body construction, and the manufacturing of tanks and containers. It is also employed in situations where precise edge preparation for a butt weld might be difficult or impractical. The amount of overlap and the welding parameters are critical factors in achieving a sound and effective laskohitsaus joint.
