The main stages and types of welding electrode production control

Raw materials and consumables, semi-finished products and finished products are subjected to careful analysis and study.

The entrance control carried out by the technical control service allows you to check the suitability of new batches of materials and raw materials entering production. The indicators that the materials and raw materials must meet are specified in the relevant manufacturer’s documentation.

The technical control service performs laboratory analysis, visually examines materials and raw materials for compliance with standards. It is checked along the way:

• packaging;
• marking;
• certificates and other accompanying documents;
• supply status, etc.

The frequency of the current control is determined by the company’s management. It can be carried out every work shift, relate to a batch of finished products or a separate technological stage.

Not only representatives of the control department should take part, but also workers, along with production foremen, responsible for a specific production stage. For example, at the stage of crimping bars, the thickness of their coating is studied, deviations from standards are established, etc.

During the production of electrodes, not only raw materials, blanks or finished products are subject to control, but also equipment. Such control is called operational and determines the state of:

• tools;
• equipment;
• production lines and their sections;
• control and measuring devices;
• modes and operations;
• semi-finished products.

Another type of control is assigned to the technical control service – acceptance control. It involves checking the compliance of the quality and other characteristics of the finished electrodes with the regulatory documentation for each individual brand, size, type, etc.
