Gap analysis process and shunting analysis process

GAP ANALYSIS AND SHUNTING ANALYSIS

Gap analysis:- when there is a process of joining two parts either by welding or any other medium there should not be a gap in between two metal near joinery area after joining. If there is a gap that appears after welding or sporting or any other way it may cause the failure of that part or body in the field. Also, gets get rejected by an aesthetic point of view. So In the gap analysis study, we use to plan first about how we should go trace gaps in parts and find out the root cause for that gaps. After making planning from where we went start with our team we have to prepare a proper format for various fixtures, stations, robots ( ITG Gun in case of manual ), and various subparts of the big assembly. After making formate we have to physically visit station to station with our team to find out gaps and how it's gone create. After discussing with the team take corrective preventive action so that we can extract gaps from parts to make it best in performance. Also, we have to plan audits for all of those gaps we arrested on a regular basis. In this way, gap analysis is carried out.

Shunting analysis:-  Whenever we do spot welding either by using ITG gun or robot spot welding, high current- voltage ratio flows throughout the electrode. That current-voltage ratio is set by us as per our requirement. But sometimes we are not aware of gun or robot arm touch to parts another surface area too during its sporting operation. Gun's/robot's tip fitted area should have to touch only to the surface where we have to weld than that current-voltage ratio supply fully through the metal and proper weld will be done. But here if other surfaces of gun touch to other surfaces of parts then there will be current bypass started this current bypass is known as shunting.
We have to form a team to study over that Shunting analysis. Discuss the problem and make blueprints of how we will go extract that shunting issue. Then again have to prepare a format for this and carried out some changes in gun movement or sometimes in the fixture as well. In this way, the shunting analysis carried out.
