Abstract
The invention discloses a kind of welding procedure of heating furnace pipeline steel alloy, including the following steps: prepare SA-213 T22 material pipeline and each one, SA-213 T5 material pipeline, and carries out retaining wall on slope；The pipeline of the groove two sides at least range of 20mm is polished using wire brush, wiping processing, removes the greasy dirt on surface and water stain, it is spare；Two branch pipe(tube)s fix spot welding using argon arc welding wire, spot welding is circumferentially uniformly distributed everywhere, is welded.Operation of the present invention is convenient, cost reduces, and without leading to argon gas protection at the welding back side, disappear hydrogen to weld seam without postwelding and stress-removal is heat-treated.
Description
Technical field
The invention belongs to heating equipment technical fields, and in particular to a kind of welding procedure of heating furnace pipeline steel alloy.
Background technique
Existing such boiler tube different alloys steel, by taking SA-213T5 and SA-213T22 welding as an example, it is contemplated that this kind of material is resistant to
Hot environment, ductility are excellent, are alloy steel, when formulating welding procedure, i.e., to consider to weld the pre- of first two steel alloy
Hot temperature need to reach the requirement of lowest side base material, also to consider postwelding disappear hydrogen heat treatment measure and postwelding stress-removal heat treatment measure
The follow-up time difference avoid causing due to the not in place of which step to guarantee the postwelding quality of weld seam and its two sides base material
The generation of the stress cracking of welding base metal or weld seam, delayed crack or hydrogen induced cracking.
It is general to select the alloy to match with both base materials of T22 or T5 when common process mostly uses greatly argon arc welding at present
Steel argon arc welding wire is welded, and still, is welded according to steel alloy welding wire, its preheating just must be taken into consideration, disappear hydrogen, postwelding of postwelding disappears
The treatment measures of stress, and the boiler tube of practical furnace body can be usually limited because of position, operating space etc. at the scene in installation process,
Cause to weld backside gas protection difficulty, preheating and subsequent heat treatment measure operating difficulties, or even can not execute, therefore, having must
It studies and a kind of protect, preheats, the welding procedure of the hydrogen that disappears, stress-removal without welding back side ventilation.
Summary of the invention
To solve the deficiencies in the prior art, the purpose of the present invention is to provide a kind of easy to operate, costs to reduce, and is not necessarily to
It welds the back side and leads to argon gas protection, weld seam disappear the heating furnace pipeline steel alloy of hydrogen and stress-removal heat treatment without postwelding
Welding procedure.
In order to achieve the above objectives, the present invention adopts the following technical scheme that:
The welding procedure of heating furnace pipeline steel alloy, including the following steps:
S1, prepare SA-213 T22 material pipeline and each one, SA-213 T5 material pipeline, and carry out retaining wall on slope；
S2, the pipeline of the groove two sides at least range of 20mm is polished using wire brush, wiping processing, removes the oil on surface
It is dirty and water stain, it is spare；
S3, two branch pipe(tube)s fix spot welding using argon arc welding wire, spot welding is circumferentially uniformly distributed everywhere, is welded.
Preferably, in abovementioned steps S1, retaining wall on slope is single side double V-groove, and machining angle is unilateral 35 ° ± 2.5 °.
More preferably, in abovementioned steps S1, retaining wall on slope root face height is 0 ~ 1mm.
It is highly preferred that argon arc welding wire is that included coating welds protection type H in above mentioned step S312Cr26Ni21Si(S310 it) welds
Silk, specification Ф 2.5.
It is further preferred that in above mentioned step S3, welding current 100A ~ 140A, voltage 12V ~ 16V.
Specifically, in above mentioned step S3, speed of welding 8cm/min ~ 10cm/min.
Preferably, in above mentioned step S3, temperature≤150 DEG C between road are welded.
The invention has the beneficial effects that: the welding procedure of heating furnace pipeline steel alloy of the invention is easy to operate, at
This reduction carries out disappear hydrogen and stress-removal heat treatment to weld seam without postwelding, both solved without leading to argon gas protection at the welding back side
Welding can not the logical protection gas in the back side the problem of, also solve and disappear hydrogen and stress-removal because position or space limitation lead to not postwelding
The problem of heat treatment, while steel alloy boiler tube intensity after welding is high, thermal stress is small, appearance of weld, in beautiful color, and quality is closed
Lattice.
