Material: Carbon steel

S35C×STKM13B×S35C
Bonding dimensions: φ65×t1.6
Conventional technique: Arc welding
Purpose: Improved quality

Reduced cost

Reduced weight

Improved environment

Issues to be resolved

● Reduced unbalance required in response to demands for low vibrations.
● There are many yoke bonded part fit shapes, and improving productivity was a problem.
● Discovery of welding defects is difficult, special cost required for inspection.

Adoption merits

● Significant reduction in unbalance, contributing greatly to reduced vibration.
● Unification of yoke bonded part shape to butt weld, elimination of cutting processsimplification of machining processes, fewer line workers, resulting in significantly improved productivity.
● Zero defective part outflow by managing pressure welding conditions, resulting in dramatically improved inspection costs. Zero shipped product defect rate!!
● Weight reduction due to improved bonding strength contributes to technological breakthrough.
● Reduced costs and reduction in secondary welding materials to zero results in significantly reduced power consumption.
