What are the formulas for calculating the flatness of a 2-meter welded flat plate?

Welding flat plate
It is a basic platform for welding work. Our products are all manufactured in accordance with B/- standards. The products are made of stiffened plate type and box type. The working surface is rectangular, square or round. Material,-,-. The working surface adopts scraping and grinding technology, and the working surface can be processed with shaped grooves, dovetail grooves, round holes, long holes, etc. Product specifications: *3*, (Special specifications are produced according to the drawings provided by the purchaser) The product is best used in an ambient temperature of ℃. Vibration should be avoided during use to avoid affecting the use effect.
Calculation formula for flatness of welded flat plate:
Grade: (+/) Grade: (+/)
Grade: (+/) Grade: (+/)
Grade: ( +/) Level 3: (+/)
Welding flat plate
(Welding platform) Purpose: used for welding process of workpieces. Different from riveting welding flat plate, there are no holes on it, and the working surface is flat or shaped groove.
Product processing technology: full-type models and tooling rrr full-type casting rrr casting artificial aging treatment rrr rough machining rrr secondary artificial aging rrr finishing rrr manual scraping rrr inspection qualified rrr a series of packaging processes to ensure the quality of the product high quality.
Welding flat plate
(Welding platform) Material: High-strength cast iron The working surface hardness is good.
Accuracy of welding flat plate (welding platform): It is implemented in accordance with the national standard metrology verification regulations, and is divided into four grades: , , , and 3.
