Auxiliary nozzle for gas welder

The present invention relates to an auxiliary nozzle for a gas welder, capable of stabilizing a welding work by forming a protective layer for an original torch flame as gas is auxiliary supplied so that the range of a torch flame can be expanded to the outside of a base subject to a gas-welding work, and of representing superior welding efficiency as the temperature of the base is increased due to the enlargement of the torch flame range. The auxiliary nozzle of the gas welder according to one embodiment of the present invention includes: an auxiliary nozzle body that is formed in the shape of a ring to detachably coupled with an outer circumference of a front end portion of a gas welding nozzle provided in one side therein with a first fluid passage allowing the internal circulation of cooling water and provided in an opposite side thereof with a second fluid passage allowing gas to be supplied downward; a mesh member located at a lower portion of the auxiliary nozzle body so that gas flowing through the second fluid passage is uniformly supplied downward; a guide member that is screwed with an outer circumference of the auxiliary nozzle body, in which the mesh member is located, fixes an outer portion of the mesh member thereto, and extends downward in such a manner that the guide member is bent inward, thereby preventing gas supplied through the mesh member from being dispersed; and a separation nozzle that is detachably screwed with the outer circumference of the gas welding nozzle coupled with the auxiliary nozzle body and fixes an inner portion of the mesh member thereto.

Heating device for preventing deformation of the iron plate of the present invention is to heat the member in advance in order to prevent deformation due to the assembly of the member 1, the motor-driven body 110 running on the basis of the member, and such a body portion Rotating holder 120 having a multi-joint structure, a pair of torch portions 130 supported by the holder portion and arranged back and forth in one direction of the body portion, and a plurality of guide rollers in the width direction of the body portion. A guide portion 140 is disposed so as to be spaced apart and inclined so that the body guides the guide reference surface 1a of the member, and is installed on the body to detect the end of the member, detect gas leakage, and block gas supply. It includes a sensor unit 150 for implementing. 몸체부, 홀더부, 토치부, 가이드부, 센서부 Body, Holder, Torch, Guide, Sensor

Electric silver contact made by filling furrow - is monitored using TV camera during continuous mfg. process

The electrical contact consists of a metal e.g. silver. Alternatively a metal alloy is used. It may be deposited onto a support and seated either on top of the support, or on a pedestal, or in a recess in the support. A furrow (1) is formed in the support and its filling up with metal during the production of the contact on a continuous production line is monitored by a television camera with photodiodes. The metal alloy filling the furrow may contain silver, copper, zinc and cadmium and is intended to produce contacts which have a long life.

Guide device, particularly for use in welding

GUIDE DEVICE, PARTICULARLY FOR USE IN WELDING 5 Guide device for use in the processing, in particular welding, of curved surfaces, in particular pipe surfaces, comprising a flexible elongate body provided with a guide for processing means; tensioning means for tensioning the flexible body around the curved surface; wherein the flexible 10 body is provided along its length with indicators arranged according to a determined pattern, this pattern being such that a determined position along the flexible body can be inferred on the basis of the detection of the indicators.

Pressure shock absorbing valve for welding systems and the like

580,816. Fluid - actuated valves. BAXTER, B., and KANDARIAN, S. M. March 7, 1944, Nos. 4249 and 4250. Convention dates, Feb. 22, 1943, and Jan. 31, 1944. [Class 135] A valve suitable for insertion between a manual regulating valve on a gas storage vessel and the reducing valve in a gas welding system to prevent pressure surges reaching the reducing valve comprises a valve member 14 retained open by a spring 11 and having flutes on its external surface through which the gas passes to the outlet 13. The end of the valve is recessed at 18 and a-bleed passage 19 is controlled by a screw 22. When a sudden high inlet pressure exists, the valve 14 is closed and the gas leaks through the bleed passage 19 until the pressure in the outlet gradually increases and the valve again opens. In a modification shown in Fig. 4, the end of the valve 14a has a cavity 18a into which projects the end 25 of a fitting 24 on the inlet end of the housing ; this arrangement increases the effect of the sudden high pressure on the closing of the valve. The bleed passage is formed in this case around the thread of the screw 22 by making the bore 19a in the valve oversize before tapping ; a filter disc 27 is fitted adjacent the head of the screw 22.
