QH Spray Welding Torch

QH Spray Welding Torch
Product Detailed
Applicable alloy powder: nickel base self-fluxing alloy, cobalt base self-fluxing alloy and so on

QH-1/h(2/h)

Introduction

Specific tool for one step oxyacetylene flame spray welding. Advantages:1. Stable flame combustion, unlike to be annealed and broad adjustment range for flame power;2. Good at powder absorption and feed, uniform in powder amount adjustment.3. Fluent powder feed, concentrated power beam, without any block..

QH-4/h

Applicable alloy powder: nickel base self-fluxing alloy, cobalt base self-fluxing alloy, iron base self-fluxing alloy, copper base self-fluxing alloy and WC involved self-fluxing alloy.Advantages of one-step spray welding: small input thermal quantity to base, small base deformation, quick spray welding speed, high powder utilization rate and self-adjustment for spray welding thickness. This spray welding torch adopts the ejection and absorption mode.
