Mathematics · Welding Heat Input
A 1 m long steel plate is welded by a manual arc welding process using a welding current of 100 A and an arc voltage of 20 V with a welding speed of 250 mm/min. If the process efficiency is 0.8 and surface resistance is negligible, what will be the total heat input for welding the entire length of the plate?
