For welding titanium-steel composite plates, how should the groove be designed?
Thread Content
For Q345R+TA2 composite plates with a thickness of 32+3 mm, how should the groove for the Q345R base layer be designed? Should a symmetric X-shaped groove with a root margin of 2+1 mm be used, or an asymmetric groove? And what dimensions should be reserved on the upper and lower sides?
It is recommended to use a symmetrical X-shaped groove with a root face thickness of 2+1 mm. Such a groove facilitates full penetration, ensuring weld quality. Asymmetric grooves may increase the difficulty of welding and are not conducive to weld formation. .
Just draw it as you said – X-shaped; the back side needs to be polished as well before the backing plate is attached
