焊接坑
英文
bell hole-
Bell hole welding
坑內焊接Bell - hole welder
坑內焊接工Cracking failure of centrifugal compressor ' s impellers was analyzed, the welding craters in the impellers led to stress concentration. the unsteady gas flow accelerated the development of cracks in the impeller
摘要針對某石化公司離心壓縮機葉輪多次發生開裂、掉塊等故障以及裂紋形成機理進行了分析。分析結果表明了葉輪開裂原因系疲勞開裂，葉輪焊接缺陷產生了焊接弧坑，造成表面應力集中，氣流激振加速了裂紋擴展。Are there pits on both sides of axe ? was it connected by being forged at the same time with grip nipped on both sides of axe
斧子的兩邊是不是都有坑？把柄夾住斧子兩邊同時打鍛焊連接的嗎？Type nhss wire rope pulling hoist is widely suitable for use in bridge - construction, laying of large - size pipes, installation and adjusting of machinery an electric apparatus, and large reaction tower of petrochemical industry ; the installation and alignment of storage tanks ; erecting, fitting, welding and alignment of masts, steel concrete timber structures ; laying and translocating of rails and sleepers ; loading and unloading bulky heavy goods during transportation. cable tensioning ; demolishing of gallery supporting logs ; stacking forrestry wood ; and othersimilar cases. the hoist of this series is especially suitable for use in narrow working sites of limited space, where the job is high above the ground or in open air places, in tunnel of deep well, where no power for traction or lifting is available
Nhss型鋼絲繩手扳葫蘆可廣泛用於建築施工、大型管道鋪設、機電設備和石油化工大型反應塔、儲罐的安裝、校準、鐵塔及其它鋼木結構的豎立、拼裝焊接、校準、鐵軌、枕木的鋪設、移位、交通運輸中笨重貨物的裝卸、電線張緊、坑道支撐木的拆除、林區木材的集放等等，對于局部空間受到限制的狹窄工作場所、高空作業、野外作業、坑道、深井作業和無機電供能場所的各種牽引、提升作業、選用本系列產品尤為適宜。Q37 series shot blasting machines have a non - silo structure, and the iniside strucrure use special anti - abra - sion cast iron for protection. the lifting hook can automatically revolve, move up and down, advance and retract, they are suitable for surface cleaning and surface and surface and surface and surface reinforcing for all kinds of iron casting parts, forged pieces, and heat - treated pieces in large, medium and small qualities
該系列拋丸機採用無地坑結構，室內全部採用特種耐磨鑄鐵防護，吊鉤實現了升降、自轉、進出自動化，它適應于多種、大中小批量的鑄鐵件、鑄鋼件、鍛件、焊接件及熱處理件的表面清理或強化。When the welding current is added, on the one hand, the section of arc will more or less increase, so the fusion width will increase ; on the other hand, the depth of arc crater will increase
焊接電流增加時，一方面是電弧截面略有增加，導致熔寬增加，另一方面是電流增加促使弧坑深度增加。When the welding current is added, the quality of heat of the arc will increase, so both the volume of molten puddle and the depth of arc crater will all increase, and the weld depth will increase when the weld is cooling
焊接電流增加時，電弧的熱量增加，因此熔池體積和弧坑深度都隨電流增加，所以冷卻下來后，焊縫厚度就增加。分享友人
