Abstract
The invention discloses a welding preheating method for an arc-shaped steel component. The method comprises the steps that firstly, the arc-shaped steel component is erected on a locating support; then, a flame heater mounted on a round rail in a sliding manner is moved along the round rail, meanwhile, the height of the flame heater is adjusted, and it is guaranteed that the flame heater is aligned to the welding position of the arc-shaped steel component; and finally, the flame heater is started, and the flame heater is moved along the round rail to preheat the welding position. According to the welding preheating method, the flame heater is firstly adjusted on the round rail to be aligned to the welding preheating position of the arc-shaped steel component, and it is guaranteed that the preheating locating is accurate. A controller is adopted for automatically controlling the moving rate and starting of the flame heater, it is guaranteed that the preheating temperature reaches the set temperature range value, and welding work efficiency is guaranteed.
Description
Technical field
The present invention relates to steel structure welding field, specifically a kind of welding pre-heating mean of arc-shaped steel component.
Background technology
Before steel structure welds, in order to ensure quality and the speed of welding, before welding, preheating can be carried out to welding position.Existing pre-heating mean adopts artificial hand-held flame gun to carry out preheating mostly, and the time that this preheating method generally spends is longer, and welding preheating position preheat temperature is uneven.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of welding pre-heating mean of arc-shaped steel component, and its preheating position accurate positioning, preheating speed is fast.
Technical scheme of the present invention is:
A kind of welding pre-heating mean of arc-shaped steel component, first arc-shaped steel member frame is located on positioning support, then the fired heater be slidably mounted on circuit orbit is moved along circuit orbit, adjust the height of fired heater simultaneously, ensure that the welding position of arc-shaped steel component aimed at by fired heater, finally start fired heater, fired heater moves along circuit orbit and carries out preheating to welding position.
While described fired heater carries out preheating, the temperature of the welding position of temperature sensor Real-time Collection arc-shaped steel component is transferred to controller, and controller controls the translational speed of fired heater on circuit orbit makes the preheat temperature of welding position reach the temperature range value of setting.
Described fired heater is connected with described controller, and after preheating position has adjusted, controller controls fired heater and starts.
Advantage of the present invention:
First the present invention regulates fired heater on circuit orbit, makes it aim at the welding preheating position of arc-shaped steel component, ensures preheating accurate positioning; The present invention adopts controller automatization to control rate travel and the startup of fired heater, ensures that preheat temperature reaches design temperature value range, ensure that the operating efficiency of welding.
Detailed description of the invention
A kind of welding pre-heating mean of arc-shaped steel component, first arc-shaped steel member frame is located on positioning support, then the fired heater be slidably mounted on circuit orbit is moved along circuit orbit, adjust the height of fired heater simultaneously, ensure that the welding position of arc-shaped steel component aimed at by fired heater, finally start fired heater, fired heater moves along circuit orbit and carries out preheating to welding position.
Wherein, fired heater is connected with controller, after preheating position has adjusted, controller controls fired heater and starts, while fired heater carries out preheating, the temperature of the welding position of temperature sensor Real-time Collection arc-shaped steel component is transferred to controller, and controller controls the translational speed of fired heater on circuit orbit makes the preheat temperature of welding position reach the temperature range value of setting.
