TL;DR: In this article, a method of welding includes a first primary welding step of carrying out a friction stir welding on the abutting portion of metal members from a first surface of a metal member.
Abstract: A method of welding includes a first primary welding step of carrying out a friction stir welding on the abutting portion of metal members from a first surface of a metal member. In a second primary welding step, the abutting portion is friction stir welded from the reverse face side of the member, while penetrating a stirring pin of rotation tool in a plasticized region formed in the first primary welding step.

TL;DR: In this paper, the authors present the manufacturing process for compact aluminum heat exchangers (e.g., micro-channel heat exchanger) using CAB and the principles of brazing sheet metallurgy, filler metal selection and application are described.
Abstract: :
Compact aluminum heat exchangers are widely used in the automotive industry. The market in the heating, ventilation, air conditioning and refrigeration (HVAC&R) industry is expected to grow. Controlled atmosphere brazing (CAB) is the state-of-the-art mass production technology. This chapter presents the manufacturing process for compact aluminum heat exchangers (e.g. micro-channel heat exchangers) using CAB. Suitable aluminum alloys are introduced and the principles of brazing sheet metallurgy, filler metal selection and application are described. Fluoride fluxes and recent developments in flux modification and application methods are discussed, and wetting and flow behavior of molten aluminum filler metals during brazing are explored. Some phenomena due to filler/base metal interactions are included. Recent developments of CAB heat exchanger materials with enhanced corrosion resistance are reviewed, and corrosion testing methods are discussed.
