Q:How to hollow square steel welding
Because the hollow steel thin wall, the use of electric welding should be used for small diameter with 2.5 electrodes, current should not be too large, can be around 100.
Q:Square steel and C steel which is better?
Then use the square. Beautiful C steel, general color steel is not used. See you square high-rise, is firmly with the 100 by 100.
Q:How to make the steel arc
If reinforced by 1. fold 2. arc bending machine flame cutting machine 4. fold 3. baking arc building arc roll can be solid steel grip bending machine processing.
Q:The water was poured into the square on how to prevent rust after treatment
Of course, all can be cloth, face sassafras. After the surface has been cleaned, it is better to put rust on the inside and outside surfaces and store them.Then is the steel material after storage should always check, if there is corrosion, corrosion layer should be removed.Finally, the corrosion of the more serious square steel, rust should not be long-term storage, should be used as soon as possible.
Q:Reinforced concrete and steel stairs to do the stairs which is better
The rectangular steel tube is also not easy to makeThe stairs were made, and there was no concrete, and the stairs were steady and durable. Easy to vibrate and rust.
Q:TIG welding of stainless steel plate and steel, how to regulate the argon arc welding
1 current 60-80, air flow 0, 5With 2 plates and square steel welding and 1 identical, square and square steel welding current is available in 120, with stronger welding flow unchanged.30, 2 of the plate welded iron angle iron, it is difficult to weld, the plate is too thin.4, black needle and gun mouth flat, go in a little can also.5 general gas stations are filled with large bottles of change. 13 presses per bottle. 8L only do the spare, easy to carry, only do the skeleton and winding, spot welding, sealing up can do 40 to 50.7 welding galvanized sheet iron with a lot of trouble. Try it and you'll see. The iron steel welding line, is not strong.
Q:Why is a point of penetration of 2 square steel welding
Electrode selection 2, 0J422, welding current about 80, if conditions permit, you can use carbon dioxide welding, welding process is very good grasp.
Q:What is the use of square steel keel or welding steel canopy
Sunshine board: advantages and characteristics of canopy cover top plate endurance detailed materials: flame retardant of spontaneous combustion temperature of 630 DEG C PC endurance board (wood 220 degrees C), by the national quality supervision and testing of fire building materials testing center, PC board of GB combustion (8624-1997 flame retardant grade B1), which belongs to the flame retardant engineering materials. Chemical corrosion resistant PC resistance board has good chemical resistance and corrosion resistance. It can resist all kinds of organic acids, inorganic acids, weak acids, vegetable oils, neutral salt solutions, aliphatic hydrocarbons and alcohol at room temperature. Heat resistant and cold resistant PC endurance board has good resistance to temperature difference. It can adapt to all kinds of severe weather changes from cold to high temperature. It can keep all kinds of physical performance indexes stable between -40 and 120 degrees centigrade. The photochemical PC resistance plate has the highest transmittance in visible and near infrared spectrum. Depending on the color, the transmittance is up to 12%-88%.
Q:What is the cold drawn steel material? Why did it break?
Should be low carbon steel, easy to break, because the carbon content of steel or impurities too much, but also later that its ductility is not good, in addition, low temperature is also easy to break
Q:How to connect with steel purlin roof
1, if the structural part of the main steel structure is H steel or other profiles, that is, steel roof truss;2, if the structural part of the main steel structure is bolt ball or welded ball, that is the steel space truss, and steel space truss also belongs to the category of steel roof truss, but the steel grid is called more accurate;
