摘要： The invention relates to a single- or multi-wire welding torch (6), more specifically to a laser-hybrid single- or multi-wire welding head provided with the welding torch (6) which can be connected to a welding device via a hose pack and consists of several parts such as a torch handle, a tubular welding torch housing, a contact housing, a contact tube for each welding wire (21a, 21b), a gas nozzle (2) etc., wherein an internal insert (28) for receiving the contact tube(s) (20a, 20b) and the gas nozzle (2) is mounted in an end area of the welding torch housing. A fixing element (30) made at least partially of a flexible material is placed on the internal insert (28) or on the housing (2) for producing as required an, in particular, gas-tight connection between said internal insert (28) and the gas nozzle (2) pushed thereon. This connection can be established by the spatial extension of the fixing element. A method for the process control of a robot welding system, a gas nozzle cap and a gas nozzle (2) for a welding torch (6) are also disclosed.

摘要： The invention relates to a nozzle system (10) having a nozzle (1) for a cutting torch (3) for autogenous torch-cutting, having a nozzle body (2) with media channels for cutting oxygen, heating oxygen or heating gas for the creation of a primary flow (4). In order to clearly reduce the noise during torch-cutting, the nozzle body (2) is surrounded in a sleeve-like manner by a tube sheathing piece (5). Therein, the inner side of the tube sheathing piece (5) has lengthwise clearances (6) on the sheathing surface of the nozzle body (2) for sucking in outside air using the suction effect of the torch-cutting media for the creation of a secondary flow (7).

摘要： This invention refers to a process for achieving the total combustion of fuels, which can reduce pollution in the atmosphere, solve (in great part) the climate crisis, stop the greenhouse effect-humanity is facing, and combat global warming. The invention's field of use is very wide, for example in engines of vehicles, in engines for airplane propulsion, in engines for ships, and in other equipment for transportation, combustion, and generation of electricity. This process involves using several types of injectors and compressed air. In this regard, the air can be compressed at a pressure of 5 to ∞ ATM, be passed through a vacuum created in a pipe, and absorb fuel in the mass of the compressed air to achieve total combustion and the number of compressed air molecules necessary to cause the total combustion of one molecule of hydrocarbon, for the various types of hydrocarbons discussed herein.

摘要： A multi-part oxy-fuel cutting tip has mixture outlet passages formed in the tip skirt to form grooves. The grooves then cooperate with the tip core to form the outlet passages when the skirt is placed over the tip core. Oppositely directed circumferential inlet passages for the preheat oxygen and fuel promote rapid mixing while producing a non-rotating mixture flow. In addition, the sectional areas of the outlet passages decrease in the flow direction. The tip core has an annular chamfer at its outlet end. These features promote the rapid creation of a laminar mixture flow.

摘要： A device in a cutting torch which comprises a torch body with a valve housing and a nozzle and with a cutting oxygen duct, a heating oxygen duct and a combustion gas duct disposed in the torch, there being disposed in the torch a connection line which contains a throttling member between the heating oxygen duct and the cutting oxygen duct and wherein disposed in the cutting oxygen duct before the connection line is a valve member which permits a flow of heating oxygen to pass through the cutting oxygen duct only in the direction towards the orifice of the nozzle.The connection line between the heating oxygen duct and the cutting oxygen duct comprises at least one cooling oxygen duct (7) disposed in the nozzle which is elaborated with three sealing surfaces towards the torch body. The cooling oxygen duct (7) has a diameter which is so adapted in relation to the orifice diameter in the cutting oxygen duct of the nozzle and to the size of the heating flame that during heating of the workpiece a cooling oxygen pressure is rapidly built up in the cooling oxygen duct which prevents hot combustion gases from penetrating into the cutting oxygen ducts and that in the case of short nozzle distances to the workpiece the flow of cooling oxygen is prevented from becoming so great that the surface of the workpiece which is situated below the orifice of the cutting oxygen duct is cooled so rapidly that hole-piercing is rendered more difficult.

摘要： A multiple piece torch tip and a method of making a multiple piece torch tip. The multiple piece torch tip comprises an inner piece disposed interchangeably within an outer piece. The inner surface of the outer piece has a plurality of regularly spaced slots which decrease in size radially outward and which combine with the smooth exterior of the inner piece to form preheat orifices. The method of making the multiple piece torch tip comprises a swaging step which in one step forms the outer piece. In the swaging step a tubular blank is swaged about a ribbed mandrel. The mandrel presents a monotonically decreasing radial cross-sectional area with respect to the blank for facilitating removal of the swaged outer piece without damage thereto. Also provided is a step of forming an inner piece of a size such that the inner surface of the outer piece and the outer surface of the inner piece combine to form preheat orifice configurations.

摘要： A holder for the assembly of a conventional flame cutting torch tip (14) which provides release of the tip, and can include water cooling (42-44) of the tip during machine cutting operations. Although such tips often become fouled, the prior art has not provided sufficiently quick release for replacement purposes. The tip is held in abutment against the torch by a plurality of cam (48) actuated clamping followers (56) which wedge against the shoulder (68) of the conventional flame cutting tip when the holder is in a clamping position. The cam is operated by rotating a spring-biased (26) actuating member, preferably a circumferential ring (22), the ring being rotatable between a clamping position and a releasing position, and normally being biased by said spring into the clamping position.
