Abstract:
1. A method of welding two members at a location having asymmetrical heat sinking characteristics, the method comprising: associating a first member with a second member, said second member defining a first area and a second area in relation to said first member, said first area comprising an area where said second member overlaps with said first member and said second area comprising a non-overlapping area of said first and second members, said first area having a greater heat sinking capability than said second area; said first member having a first member welding side and a first member contact side, said first member contact side being in close association with and facing toward an adjacent surface of said second member in said first area; applying a penetration enhancing compound to said first member welding side, opposite from said first member contact side, adjacent to a junction location between said first area and said second area; and heating said first member at the penetration enhancing compound by positioning a welding electrode adjacent to said first member welding side, said penetration enhancing compound located between said welding electrode and said first member welding side, and performing an arc welding by providing an arc welding power from said welding electrode to said first member welding side, said welding power causing welding heat to penetrate said first member from said first member welding side to said first member contact side and to heat said adjacent surface of said second member to effect formation of a weld joint between said first member contact side and said adjacent surface of said second member.
