BAIJIAN - Third party testing organization
After the joint metal and filler metal melt、 they are cooled and solidified at a faster rate to form. The weld seam structure is a cast structure crystallized from liquid metal、 with coarse grains、 component segregation、 and less dense structure. However、 due to the small size of the welding pool、 fast cooling、 strict control of chemical composition、 and low levels of carbon、 sulfur、 and phosphorus、 the chemical composition of the weld seam is also adjusted by alloying to contain certain alloying elements. Therefore、 the performance of the weld metal is not a problem and can meet the performance requirements、 especially the strength is easy to achieve
