Description
Technical field
The invention belongs to post weld heat treatment field of temperature measurement in electric power construction, be specifically related to a kind of armoured thermocouple and fix
Scheme.
Background technology
At present in electric power construction production process, the universal thermocouple of temperature-measuring part of post weld heat treatment carrys out thermometric, adopts
Use 18# thin wire, pyrometer fire-end colligation is being treated that at thermometric, surface carries out thermometric.Owing to thin wire diameter is less, iron wire is
By thermometric whole body surface colligation, when high tempering processes, inconsistent with the weld seam coefficient of expansion, cause point for measuring temperature to move
Or cannot with treat to be in close contact at thermometric, and thermometric is inaccurate.
Another is to use plainly-packed thermocouple, utilizes percussion welder that plainly-packed thermocouple tip point is welded in table at temperature to be measured
Face carries out thermometric.Owing to solder joint is less, during the take-up strap of later stage heater plainly-packed thermocouple focus thermo wires with treat
Electric welding at thermometric easily departs from, and causes thermometric inaccurate.
Summary of the invention
In order to solve the problems referred to above, the invention provides a kind of armoured thermocouple fixing means, solve face of weld meeting
Produce dissimilar materials and cause the uneven consistent phenomenon of face of weld material, and solve at pyrometer fire-end contact measured temperature
Contact loosely, cause the inaccurate problem of thermometric.
The technical solution used in the present invention is as follows:
A kind of armoured thermocouple fixing means, comprises the following steps:
1), after mother metal welding procedure, commissure self-inspection is qualified；
2) one section of welding wire identical with mother metal commissure material is intercepted；
3) by step 2) in the end point of welding wire that intercepts be welded in weld seam and treat thermometric surface, welding wire during welding machine spot welding and intercepting
Welding wire material identical；Armoured thermocouple hot junction is placed on the centre position of welding wire, welding wire other end point is welded in temperature to be measured
On surface, so that this welding wire compresses pyrometer fire-end；
4) butt welded seam carries out heat treatment；
5) grind off at the spot welding of welding wire with polishing machine after heat treatment, polish face of weld.
Above-mentioned armoured thermocouple fixing means step 2) in, described welding wire is argon-arc welding wire, its a diameter of 2.4mm or
2.5mm, intercepted length are 40-55mm.
The invention have the benefit that
1, use the welding wire as weld seam material to carry out spot welding and fixing thermocouple, make in heat treatment process, the coefficient of expansion one
Sample, welding wire compresses pyrometer fire-end all the time at pending face of weld, thermometric accurately, reliable.
2, the welding wire material of two ends spot welding is as weld seam, and surface does not penetrates into other material, is conducive to face of weld
The uniformity concordance of material.
3, the method is simple to operation, and armoured thermocouple mechanical strength is high, flexible install and use, dynamic error little.
