TL;DR: In this article, a finite element (FE) model was established to examine thermal-mechanical response during the entire welding process, and two additional heat sources on both sides of the welding line were applied to achieve TTT treatment.

TL;DR: In this article, a method for fabricating girders having depths and/or web dimensions greater than standard rolled beams is described. Butts welds are used to join the web members of a girder to flange members.
Abstract: My invention relates to built-up steel beams naving solid webs or inserted web members joined to flange members by continuous butt welds. My invention relates particularly to girders having depths and/or web dimensions greater than standard rolled beams, and the method of fabricating same....

TL;DR: In this paper, the benefits of using Magnetic Pulse machine which is belong to Non-conventional machine instead of conventional machine is discussed, which is used for joining dissimilar metals, and for forming and cutting metals.
Abstract: In this paper, the benefits of using Magnetic Pulse machine which is belong to Non-conventional machine instead of conventional machine. Magnetic Pulse Technology is used for joining dissimilar metals, and for forming and cutting metals. It is a non contact technique. Magnetic field is used to generate impact magnetic pressure for welding and forming the work piece by converted the electrical energy to mechanical energy. It is enable us to design previously not possible by welding dissimilar materials and allowing to welds light and stronger materials together. It can be used to weld metallic with non metallic materials to created mechanical lock on ceramics, polymers, rubbers and composites. It is green process; there is no heat, no radiation, no gas, no smoke and sparks, therefore the emissions are negligible.

TL;DR: An aluminothermic welding device for the butt welding of two metal members such as railroad rails is described in this article, where a mould and a crucible are formed with mutually complementary respective depressions and/or reliefs.
Abstract: An aluminothermic welding device. The device, which is for the butt welding of two metal members such as railroad rails, comprises a mould and a crucible the respective upper and lower faces of which are so formed with mutually complementary respective depressions and/or reliefs as to enable the crucible to be placed on the mould in a position in which the discharge aperture of the crucible and the pouring bush of the mould are coaxial and turned downwards and upwards respectively. This ensures the correct positioning of the crucible in relation to the mould. The crucible can also be constructed in a form enabling it to be used once and from a material selected for this purpose and advantageously differing from the material used for the mould.

TL;DR: In this paper, Thompson et al. describe a method for butt welding of metal strips by moving the strips at a relative acute angle, up to a welding head 28, providing a high frequency electric current, whereupon the edges of the strip are heated when spaced apart, whilst being held in slightly overlapped relationship, and then moved transversely, so that they wipe across each other and are welded.
Abstract: 1,142,922. Welding. THOMSON CORP. 9 May, 1967, No. 21573/67. Heading B3B. Metal strips 16, 18 are butt welded by moving the strips at a relative acute angle, up to a welding head 28, providing a high frequency electric current, whereupon the edges of the strip are heated when spaced apart, whilst being held in slightly overlapped relationship, and then moved transversely, so that they wipe across each other and are welded. The apparatus 10 for carrying out the operation comprises a base 20, adjustable guide rolls 22, strip tensioning rolls 26, welding head 28, edge forging rolls 34, 36, compression rolls 46, 48, pinch rolls 50, 52, and where one of the strips is of zinc-coated steel, means for supplying carbon dioxide, or nitrogen to the welding area. Rolls 34, 36 are supported in fixtures 38, 40, and are held against the strips by a pneumatic cylinder 42. The strips may be galvanized cold rolled steel, stainless steel, or non-ferrous metal, and they may be of the same, or different materials. Guide roll stands 24 are insulated at 56, rolls 26 are made of polyurethane, and rolls 34, 36 are of bronze, brass, or ceramics. Rests 64 are provided for the strips and are adjustable about pivots 66 so as to vary the approach angle between the strips. Electrodes 80 are secured to arm 82 pivotable at 84, and engage the top faces of the strips. Rolls 46, 48 are disposed slightly rearwardly of rolls 34, 36 and are held in contact with the composite strip by springs 100, whose rating can be adjustable. In operation, strips 16, 18 are taken from reels insulated from each other, are guided by rolls 22, tensioned by rolls 26, heated to a plastic state by electrodes 80, squeezed by rolls 34, 36, followed by rolls 46, 48, and then the composite strip is removed by rolls 50, 52 to a wind-up reel.
