Abstract

The invention discloses a spherical head inner wall welding linear speed automatic setting method, and relates to the technical field of welding, in particular to a spherical head inner wall surfacing welding linear speed automatic setting calculation and implementation method. The method comprises the following steps: 11, assembling a spherical seal head: assembling the seal head on a positioner, wherein the rotating central axis of the seal head coincides with the rotating central axis of a turntable of the positioner; 12, data input, wherein the ball diameter of the spherical end socket and the welding linear speed are input into a positioner; 13, a mathematical model is established, wherein a calculation formula v = 2pi SR [omega] sin [alpha] is obtained through modeling; the rotation speed is automatically calculated through the formula v = 2pi SR [omega] sin [alpha] according to the detected tip-over angle and the input ball diameter and welding speed of the spherical head; and 14, welding. According to the technical scheme, the problems that in the prior art, an existing welding positioner can only set the rotating speed of a rotating shaft instead of the linear speed needed in the actual welding process, and an operator needs to repeatedly adjust the rotating speed of the positioner and measure the actual linear speed of the welding position through meter pinching are solved; the problems that the actual linear speed of the welding position is close to the needed welding speed, the rotation speed needs to be manually adjusted again after the tip-over angle of the end socket is changed, the welding speed adjusting efficiency is low, errors are large, the welding efficiency is reduced, and the welding quality is unstable are solved.

Description

technical field [0001] The invention discloses a method for automatically setting the linear velocity of the inner wall of a spherical head, relating to the field of welding technology, and in particular to a calculation and implementation method for automatically setting the linear velocity of the inner wall of a spherical head for surfacing welding. Background technique [0002] When the spherical head, especially the large spherical head, is used for automatic surfacing welding of the stainless steel layer on the inner wall, the torch is generally in a vertical state during welding and is fixed. In order to ensure the welding quality, the welding position is required to be in a horizontal position, so the head needs to be placed Installed on the rotary table of the welding positioner for welding. The welding positioner has two axes of tilting and turning; the tilting axis is parallel to the rotary plate, and is used to adjust the angle between the spherical head and the h...

Problems solved by technology

In the actual operation process, this rotational speed is only a reference. The actual welding speed needs to be measured with a pinch meter, or calculated by measuring the radius of gyration, and each path is different, so operators often visually measure the welding speed, and need to Adjust the rotation speed according to the change of the welding position, which affects the welding efficiency and causes the instability of the welding quality
