Paton Electric Welding Institute of the National Academy of Sciences of Ukraine popup.description2 The research allowed to establish basic technological methods of laser and hybrid (laser-arc and laser-plasma) welding, which through the use of pulse modulation radiation you get high-quality connection of thin sheet (6 mm) materials like aluminum alloy 1560 (with durability 85% of the strength of the base metal) and stainless steel SUS304 (strength equal to the strength of the base metal), which in its mechanical properties are acceptable for use in missile technology and other critical structures. Established that for quality butt joints of sheet aluminum alloy 1560 in the case of a laser, and in the case of laser-plasma hybrid welding linear energy need to invest about 15 ... 30 J / mm in the depth of one millimeter in penetration speed range 100. ..300 m / h. In the case of laser and laser-arc welding steel SUS304 need to invest energy running about 15 ... 50 J / mm one millimeter depth of penetration in the speed range of 75 ... 400 m / h. The use of plasma arc and components in hybrid processes allows a mechanism by increasing the heat absorption capacity of the base metal to reduce radiation power by replacing its power source to plasma ratio of about 1: 1, which significantly reduces the cost of equipment.
