Description
Technical Field
The invention belongs to the field of electroslag pressure welding butt joint and measuring tools, and particularly relates to an adjustable calibration type electroslag pressure welding tool.
Background
The electroslag pressure welding of reinforcing steel bars is a welding mode in which two reinforcing steel bars are placed in a vertical or oblique (gradient is in a range) butt joint mode, an arc process and an electroslag process are formed under a drier layer by utilizing a connecting current to pass through gaps of the two reinforcing steel bars, arc heat and resistance heat are generated, the reinforcing steel bars are melted, and pressurization is completed. The vertical steel bar electroslag pressure welding is a steel bar welding technology initiated in China, has the characteristics of convenient construction, low cost, simple operation and the like, and is widely applied to the field of vertical steel bars of buildings and other structural members in China.
However, in the welding construction process of the existing engineering, it is found that an excessive inclination angle generated between upper and lower welding bars may be caused by an error in the welding process during the welding of the joint; the upper reinforcing steel bar is offset by an axial distance exceeding the diameter of the reinforcing steel bar; the height of the solder bump does not meet the standard.
After the electroslag pressure welding is finished, workers are required to measure the welding ladle, and appearance detection of the welding ladle is carried out through observation; measuring whether the projection height of the welding bag meets the requirement by the tape measure; measuring tape measures and detects vertical reinforcing steel bars. When the welding length of the steel bar is long, a larger deflection amount of the steel bar can be caused by smaller angle deviation, and a specific value of the deflection amount generated by the steel bar cannot be directly measured through the measuring tape. With this resulting deviation, the safety of the structure may be adversely affected.
If the quality defect of welding is found only in the pouring stage, the subsequent steel bar treatment is quite troublesome, time and labor are wasted, and the steel bar can not be treated even when the difference is large.
Therefore, we propose an adjustable calibration type electroslag pressure welding tool to solve the above problems.
