Q:How to connect the base of the tower crane and the flat steel? How can it be welded and connected?
How to connect the base of the tower crane and the flat steel?:It can be punched on a flat iron and connected by screws and multiple copper wires
Q:Cold rolled flat steel standard. What is cold rolled flat steel?
Flat steel, width 12-300mm, thickness 4-60mm, cross section is rectangular and with pure edge of steel. Flat steel can be finished steel, or can be used as the blank of welded pipe and thin slab for laminated sheet rolling.
Q:Is the earthing electrode made of galvanized flat steel or bare copper wire?
The earthing device is divided into horizontal grounding and vertical grounding. The horizontal earthing body generally adopts hot-dip galvanized flat steel or hot galvanized round steel; the vertical grounding electrode adopts hot-dip galvanized steel, angle steel, steel tube, round steel and other materials.
Q:What is the tensile force of the galvanized flat steel of 20*3?
According to "hot rolled flat steel size, shape, weight and allowable deviation", GB 704-88:Ordinary class allows upper deviation +0.3mm, lower deviation -0.5mm; higher allowed upper deviation +0.2mm, lower deviation -0.4mm, the upper deviation is not to think, do not exceed the next deviation is good.
Q:What is flat steel, please? What are the specifications of flat steel?
Flat steel can be finished steel, or can be used as the blank of welded pipe and thin slab for laminated sheet rolling.
Q:Lightning protection grounding, what is called three surface welding?
When lap welding is adopted, the welding length is as follows:1, galvanized steel bar is not less than its width of 2 times, three surface welding. When the width of flat steel is different, the length of lap should be wide. Before laying, the flat steel should be adjusted straight, simmer, bend not to die, straight line should not be obvious bending, and should stand upright.2, galvanized round steel welding length of 6 times its diameter, and should be double-sided welding (when the diameter is not the same, the length of overlap in diameter should prevail).3, galvanized round steel and galvanized flat steel connection, its length is round steel diameter of 6 times.4, galvanized flat steel and galvanized steel pipe welding, in order to connect reliable, in addition to contact in itBoth sides of the site shall be welded, and the flat steel itself shall be bent in an arc to be welded with the steel pipe.
Q:How can copper clad steel ground electrode and galvanized flat steel be welded?
