Recipe! visual inspection (VT)
• Target
• The development of these guidelines and rules for the inspection and control of food products before - during - and after the welding process is in terms of visual appearance.
• scope
• Scope This instruction covers the installation and repair of all welding processes are.
General Methods and
• One of the most common methods of inspection.
• INC is simple.
• Day to day management.
• At no time should not be underestimated.
• success of technical knowledge and ability to make decisions about the acceptance or rejection of the product.
• check design drawings prior to making avoidable mistakes reveals.
• During the inspection could provide useful information that sometimes is enough to solve the problem.
• Visual inspection of the light is important (the equivalent light intensity minimum lux 500 W 100 at a distance of a meter)
• Visual inspection can only detect surface defects and macroscopic surface preparation device for non-destructive testing revealed.
Visual inspection before welding
• Control of the base metal surface flaws.
• Control Specification signs engraved on the pieces.
• Clean the surface of the paint - oil - dust - so the alarm.
• Connection Control preparation of the chamfer dimension standards EN 29692 and ISO 9692 equivalent design drawings.
• Adjust the distance of the conditions and obligations under agenda.
• Inspection of labor conditions in terms of temperature - relative humidity - SPECTRA makes general weather conditions.
• Control of welding consumables electrode being corrupt and being healthy and being healthy filler metal and powder coated.
• Control of the geometric dimensions and the distance between the spot welds spot welds in accordance with the agenda.
• Temperature-controlled preheat the WPS....
