Hybrid welding of 304 austenitic stainless steel
The high elasticity and flexibility are controlled by the joints at low heat input, which might be credited to smaller dendrite sizes. The high heat input exhibited by sample F6 can be ascribed to long dendrite sizes which lead to its low UTS value. The weld joint efficiency (η) is calculated for each sample.
