TL;DR: In this article, information pertaining to characteristics of consumables such as metal welding electrode wire and shielding gas and which characteristics are useful in connection with adjusting welding parameters in an arc welding process and selecting between operating modes in a welding system are encoded on welding wire and/or on other memory components such as bar code labels and tags.
Abstract: Information pertaining to characteristics of consumables such as metal welding electrode wire and shielding gas and which characteristics are useful in connection with adjusting welding parameters in an arc welding process and/or selecting between operating modes in a welding system are encoded on welding wire and/or on other memory components such as bar code labels and tags, RFID cards and tags, IC cards, and Touch Memory buttons, and the memory device is scanned prior to and/or at the point of use of the welding wire or shielding gas for enabling tracking of product distribution, manual and/or automatic selection of an operating mode for the welding system, manual and/or automatic adjustment of welding parameters in a given operating mode, consumables inventory, and the like.

TL;DR: In this article, the ability to relate weld strength to the welding process data, namely dissipated power and displacement of the sonotrode, in ultrasonic welding of thermoplastic composite parts with flat energy directors, is described.
Abstract: Ultrasonic welding of thermoplastic composites is a very interesting joining technique as a result of good quality joints, very short welding times and the fact that no foreign material, e.g. a metal mesh, is required at the welding interface in any case. This paper describes one further advantage, the ability to relate weld strength to the welding process data, namely dissipated power and displacement of the sonotrode, in ultrasonic welding of thermoplastic composite parts with flat energy directors. This relationship, combined with displacement-controlled welding, allows for fast definition of optimum welding parameters which consistently result in high-strength welded joints.

TL;DR: In this article, a brief review of weld simulation and residual stress modelling using the finite element (FE) method is presented, where the method of FE analysis of welded sections of P91 pipes is described.

TL;DR: In this article, the authors examined the fatigue properties of laser beam welded thin sheet aluminium and found that the cyclic strength of overlap joints with a slot weld is characterized by a two-dimensional crack-like notch between the sheets.
