Detailed explanation of spot welding process
01. Brief description Spot welding is a resistance welding method in which the weldment is assembled into a lap joint and pressed between two electrodes, and the base metal is melted by resistance heat to form a solder joint. Spot welding is mainly used in the following aspects: 1. Lap joint of s...Read more -
Why is titanium alloy a difficult material to machine
Why do we think titanium alloy is a difficult material to machine? Because of the lack of deep understanding of its processing mechanism and phenomenon. 1. Physical Phenomena of Titanium Machining The cutting force of titanium alloy processing is only slightly higher than that of steel with the ...Read more -
The difference between high-speed steel and tungsten steel is very clear!
Come to understand high speed steel High-speed steel (HSS) is a tool steel with high hardness, high wear resistance and high heat resistance, also known as wind steel or front steel, which means that it can be hardened even when it is cooled in air during quenching, and it is very sharp. It is al...Read more -
