Welding tool is a way for the blade and blade part of the connection, through the dehydration of borax, copper, ferromanganese, glass powder, solder, the high temperature melt, let alloy, high speed steel,, diamond and cubic boron nitride ceramic material such as razor blades and trough consistent tool rod sticking together, in order to achieve the demand of machining operations, a turning the most widely used for cemented carbide tool, because of the hard alloy hardness is higher, can reach the use requirement, most of the processed material and corresponding relative to other material cost is very low, so it is widely used, carbide welding tool according to the properties and processing object is mainly divided into three kinds, red handle for YG class, represented by YG6 and YG8, mainly used for cast iron, non-ferrous metals and non-metallic materials roughing, skinned, advantage is high bending strength, the disadvantage is that poor abrasion resistance, can only be used for low speed processing, yellow handle for YW classes, with YW1, YW2, mainly used for semi finished high viscosity material such as stainless steel and refined, YW class alloy high hardness, wear resistance, but the bending strength is limited, is suitable for high speed small feed processing, is a good commonality carbide, blue handle to YT classes, represented by YT15 and YT5, suitable for 45 # steel, plain carbon steel processing, high hardness, bending strength is poorer, wearability is good, mainly for roughing and semi-finishing.

Performance of welding tool.

Advantages: the welding tool structure is simple and compact; Strong rigidity and strong vibration resistance; Manufacturing, grinding and convenient; Use flexibility.

Disadvantages: the blade has been welded with high temperature, the strength and hardness are reduced, and the cutting performance is reduced. The blade material produces internal stress and is prone to crack and other defects. The handle can not be reused, waste raw materials; It is not suitable for automatic lathe and nc lathe.

Turning to cylindrical workpieces, end face of the straight head, 90 and 45 elbow tool, hole boring cutter, blind hole boring cutter, cutting, etc.

In order to make the blade weld firmly, the edge grinding is small, so it is necessary to process the groove shape on cemented carbide tool bar, and the common form of knife slot is the following.

(1) the opening groove is simple in shape and easy to process, but the welding area is small, which is suitable for the type C blade.

(2) the semi-closed groove can only be processed by milling cutter, which is difficult to manufacture, but the welding blade is firm, which is suitable for A and B blade.

(3) the closed groove clamp blade is strong, and the welding is reliable. It is used for thread cutting tool and is suitable for type E blade.

(4) the incision groove is used to cut off the cutting knife and slot cutter with small floor area, so as to increase the welding area and enhance the bonding strength, which is suitable for the D blade.

Folding welding equipment

Welding is a process of making or sculpting metal or thermoplastic plastics. During the welding process, the workpiece and solder melt into molten area, and the connection between the materials is formed when the molten pool cools and solidifies. Welding is made by heating, pressurizing, or both, making the two workpieces produce an interatomic process and a connection. Welding is widely used in both metals and nonmetals.
