In the case of cranes belonging to a special type of equipment, the manufacturing process is more demanding and can be known for the welding process used by the crane manufacturer. The control on the welding process is combined with on-site inspection and targeted special inspection. According to the quality of the equipment of the spot-checked product, check the welding process control and check whether the following requirements are met:
1. On-site welding process, welding record specification, complete and complete, welding quality is effectively controlled.
2. The welding equipment is in good condition and meets the requirements for welding.
3. Welded plates meet the relevant safety technology specifications and their corresponding standard requirements.
4. Statistics on welding quality and analysis of statistics.
5. Welding and repair, according to certain regulations for a certain maintenance management. At the same time, according to (the base metal defect repair welding), the relevant re-inspection process is carried out.
In the process of mechanical welding, it is necessary to master certain technologies and technical treatments. The use of welding processes on cranes is more stringent, and there are certain regulations and standards for the quality requirements of welding. The quality of the weld is closely related to the safety of the crane at work. However, the demand for the process is even higher. In the welding, we still need our professional staff to carry out related work. A certain detection technique is required after the welding to perform the inspection process.
Respiratory Protection is a device designed to protect the wearer from inhaling particulate matter, including airborne microorganisms, fumes, vapours and gases. There are two main categories: the air-purifying respirator which forces contaminated air through a filtering element, and the air-supplied respirator in which an alternate supply of fresh air is delivered. Within each category, different techniques are employed to reduce or eliminate noxious airborne contaminants.
Respirators range from relatively inexpensive single-use, disposable face masks to more robust reusable models with replaceable cartridges.
They are also sometimes referred to as a dust mask or a gas mask.
