Its thermal conductivity is 13.0 W / m�K . Its tensile strength is 960-970 MPa and its modulus of elasticity is 200-210 GPa . It can be joined by welding ( GMAW and resistance welding, soldering and brazing.
22.
As the heat dissipates throughout the workpiece in less than a second ( resistance welding time is generally programmed as a quantity of AC cycles or milliseconds ) the molten or plastic state grows to meet the welding tips.

In 1984, the company developed a neodymium-doped yttrium aluminum garnet ( Nd : YAG ) laser welder that allowed for more precise and micro welding, and this product line became a central component of the company s business, along with resistance welding.

"' Electric resistance welding "'( "'ERW "') refers to a group of welding process in which parts to be welded are first heated to the fusion temperature by the resistance of work piece to the flow of electric current and then squeeze by mechanical pressure to accomplish weld.
25.
Competing welding processes such as resistance welding and oxyfuel welding were developed during this time as well; but both, especially the latter, faced stiff competition from arc welding especially after metal coverings ( known as flux ) for the electrode, to stabilize the arc and shield the base material from impurities, continued to be developed.
