AI Technical Summary
Technical Problem
Conventional cooling block welding methods struggle to ensure watertightness and maintain welding quality in the plug area due to insufficient welding filler material.
Method used
A method involving forming a step greater than the plug's insertion thickness in the plug insertion portion, inserting the plug to create a clearance space, and welding the plug area including this space to ensure adequate filler material distribution.
Benefits of technology
Ensures defect-free welding and prevents deterioration of welding quality in the plug area by ensuring proper filler material distribution, thereby maintaining watertightness.

Abstract
The present invention relates to a method for welding a cooling block, a method for manufacturing a cooling block for a vehicle battery pack using the method, and a cooling block for a vehicle battery pack manufactured by the method. The method for welding a cooling block according to the present invention comprises: a step of forming a step greater than the insertion thickness of a plug in a plug insertion portion of a vehicle battery pack cooling block into which a plug is to be inserted; a plug insertion step of inserting the plug into the plug insertion portion to form a clearance portion on the outside of the plug; and a plug welding step of fixing the plug by welding the plug area including the clearance portion.
