Features

◎ The welding layer is iron-based material which is good for welding.
◎ Bumps on the welding surface make the contact easy to weld with low current, and small deformation can be negligible after welding.
◎ The welded components has good appearance and high shear strength.

	The shape of bumps on the welding surface could be diamond or round etc. The thickness of welding layer (a) can be up to 20% of the total.	The thickness of the working layer can be up to 20% of the total thickness.	It is 60% of total thickness in general.

Material
