eng	Problems of Spot Welding of Al-Si Coated Martensitic Low Alloyed Steels	Low alloy high strength steels are the key materials in the design of safety parts car body structures. Contribution is dedicated to the study of boron steel type of 22MnB5 weldability, with fully martensitic microstructure due to hot stamping technology. The main objective of performed analyses is to study the differences in formation of the surface AlSi layer. Based on metallographic evaluation of welded joints, there was observed the influence of the variability of the internal structure of surface AlSi layers on the scope and the character of thermal effects.
