submit other answers - - : : most problems in welding are caused my the welding puddle being contaminated in some way. lack of shielding gas (empty tank, of wind blowing it away) lets oxygen into puddle. dirty material (rust, paint oil) allow the contaminants into the puddle, which in turn can cause...
submit other answers - - : : can not know the gear base material, welding can not talk about the problem can not answer, and specify a reasonable welding process. only that the specific material of the gear metal grades, can be based on the gear base metal, select the electrode (wire) grades [ more ]...
submit other answers - - : : vacuum sintering is to prevent the alloy in the metal element co and oxygen in the air oxidation, thereby reducing product performance. pressure sintering is in the vacuum on the basis of pressure to increase, the purpose is to change the structure of carbon products in the...
submit other answers - - : : the sealing ring is a ring with a gap seal, placed it in the ring groove in the sleeve, the sleeve rotates with the shaft, the sealing ring is pressed by gap long after the elasticity is pressed against the inner hole wall of the stationary member, can play a role in sealing...
submit other answers - - : : not really. frequency in is frequency out, unless there is some conversion circuit in between, such as a motor-generator set or some kind of inverter. you may (and should) notice, however, that a typical welding transformer is rectifying three phase ac to dc, using a full...
submit other answers - - : : weld procedures are what the engineer is supposed to develop to tell the welder how to weld to particular pieces of metal together. they can change based on metal types, position, type of joint, design efficiency of the joint, whether or not the weld is on a coded vessel...
-list some uses. . . . anwser all that you can. i had to do it for a project like years ago and i found it in one of my own notebooks. i wondered if people knew anything about this anwser. if you get the best anwser then got the most right. submit other answers - - : : . also called wolfram. . hard ....
answer reward deadline - - : : hardness, cutting speed submit other answers - - : : the coating has high hardness (tic - hv . tin - hv ), good wear resistance, can reduce the crater wear and flank wear on the rake face of the tool, and improve the durability of the tool. the coated blade has a % to %...
submit other answers - - : : the small changes in carbon content have an important influence on the microstructure and properties of the alloy. precise carbon control is a key factor and key link in the process of producing cemented carbide from crushed materials. carbon quantity control is to control...
answer reward question has expired in the process of recycling cemented carbide scrap submit other answers - - : : the formation of the cozn alloy phase must consume the theoretical amount of metal zinc. at the operating temperature, the alloy phases cozn and wc are both solid phases. in addition to...
